I'd like to run a DRC to check my clearances. In previous versions of Deluxe, it was under the Tools menu. I now have Viewmate Deluxe 11.4, but I do not see any DRC option under the Tools menu, even though the manual seems to indicate that it should still be there. Where is it located?

We have removed DRC from ViewMate Deluxe because it used the "vector DRC' method, which is very limited.It cannot handle polygons, paint and scratch or custom shapes.Since today many Gerber files contain such items, we were getting complaints from users when vector DRC provided incorrect results.We provide complete DRC and DFM in CAMMaster designer and CAMMaster.VIewMate Pro has another limited variety, called raster DRC, It is better than vector DRC, but is limited by the fact that the results depend on the resolution chosen before doing the DRC (a raster image is generated first, then DRC is performed on the image).And finally, you can run Smart DFM in ViewMate Deluxe. It has a fixed set of DRC rules that you cannot modify, but they are common for today's board fabrication, so if your design passes these checks it is very likely acceptable by most board fabricators.
